Answer:
The new 12 PM temperature should be 2.5 degrees Fahrenheit. And Dana is correct; you can subtract 1.4 from 2.5 (2.5 - ( -1.4) to find out the change in temperature from 6 AM to 12 PM on the second day.
Note:
Because of the direction the subtraction problem is set up between 2.5 and -1.4, the two negative signs will result in an addition sign according to the rules of algebra. Meaning that, the difference between -1.4 and 2.5 is approximately 3.9.
Answer:
$24.15
Step-by-step explanation:
What you do is you take 15% and make it into a decimal which is .15.
Then you times it by $21. 21*.15=3.15.
You then take the $3.15 and add it to $21 to get
$24.15 as your answer.
First, convert that into a y=mx+b form.
Move the x to the other side so y is the only thing on the left. Since you moved it to the other side of the equal sign, be sure to make that number negative (the opposite sign)
Now… you have 4y=-3x+28
Let’s get y by itself. Since you’re multiplying 4 and y, you divide everything by 4 to get your y.
That leaves you with y=-3/4x+7.
We are looking at slope, which is your m in the y=mx+b form.
That is -3/4. The answer is the last square.

The correct answer from the drop-down menu is 3.5.
<h3>What is the mean value?</h3>
The mean is the average of the numbers. It is easy to calculate add up all the numbers, then divide by how many numbers in the data set.
Therefore the population mean is the sum of the 12 data set values divided by 12
4 + 6 + 7 + 11 + 12 + 18 + 26 + 23 + 14 + 31 + 22 + 12 = 186.
Therefore the population mean
= 186/12
= 15.5.
The sample mean is given by the sum of the 4 sample values divided by 4
11 + 31 + 22 + 12
Sum = 76.
Therefore the sample mean
= 76/4
= 19.
The sample mean is more than the population mean by
= 19 - 15.5
= 3.5.

If you would like to simplify <span>(5a^2 * b^3)^0, you can do this using the following steps:
</span>
<span>(5a^2 * b^3)^0</span> = 5^0 * (a^2)^0 * (b^3)^0 = 1 * 1 * 1 = 1
The correct result would be 1.
